Liposome-encapsulated hemoglobin (LEH; TRM-645) is a novel oxygen (O(2)) carrier with a lower O(2) affinity (P(50)O(2)=40 mm Hg) than red blood cells. In contrast to cell-free hemoglobin, encapsulation prevents hemoglobin extravasation, whereas its subcellular size (230 nm) may improve O(2) delivery and limit the severity of cerebral infarction.
